Ah. The master branch is already integrated with conduit! Thanks. --Kazu

Thanks for the positive feedback Kazu! For the nullSource, you can actually use mempty, since Source is an instance of Monoid. I realize now that I didn't even think about this when I was writing http-conduit, and instead used `sourceList []` in a few places. I think in conduit 0.0.4 I'll include Data.Conduit.List.sourceNull, with a comment that it's just a type-restricted synonym for mempty. Sound good?

Hello,

I have modified Mighttpd 2 to use Conduit and it is now running on my domain, Mew.org.

Using Conduit made my code much much simpler than before. And Conduit is much easier to use especially on passing Source around and error handling. I was excited. I believe that Conduit is a right way to go. Michael, thank you for great work!

What's missing for me is null source. I added the followings to my code but I would be happy if Conduit provide them. Note that we should choose better names and parameterize their types.

eof :: PreparedSource IO Builder eof = PreparedSource    { sourcePull = return Closed    , sourceClose = return ()    }

nullSource :: Source IO Builder nullSource = Source (return eof)

Hello,

I come back to my reverse proxy work today. But I could not find wai and warp repository (or branch) based on conduit. Where can I find them?

I'd like to add that sourceNull is a rather confusing name, and sourceEmpty would be more consistent with the other libraries out there. See e.g. Data.Map.null :: Map k a -> Bool Data.Map.empty :: Map k a Cheers, Jasper On Fri, Jan 13, 2012 at 7:57 AM, Kazu Yamamoto wrote:

Yes, sounds great. Thank you.

OTOH, we've got /dev/null =). -- Felipe.

One more thing: It was easy for me to understand how to convert BufferedSource to Source thanks to "unbufferSource". But I took a time to understand how to convert PreparedSource to Source. I would like to have a helper function by giving a proper name to "Source . return". --Kazu
